*********

Absolutely not a critical one, but first run of autoreconf fails when I
use AX_CXX_COMPILE_STDCXX_14 macro from autoconf-archive (version
2016.03.20-r1 installed via portage on Gentoo), and only when I use it.
Second run immediately after it just works.

The message says "please contact...", so I did.

Hi.

See https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49901 for an 
explanation. It's partially the macro itself that is buggy:

"
This sort of behaviour is the main reason why the aclocal documentation
suggests these files not contain anything other than macro definitions[1],
so that they are not sensitive to include order.
"

Indeed. I'm merging these bugs, although there is only a little that can
be done on the automake side, as far as I can see. --thanks, karl.
